 Good place to drain tankless water heater condensate?
Author: Milliarde (TX)

I will be installing a Rinnai tankless water heater, the RUC98i. From what I understand it needs to have a 1/2" PVC attached to the "condensate drain line" on the bottom of the unit. However, I'm not sure what's the best place to drain it?

It will be in the garage, so it's not next to any other outgoing drainage (sinks, etc.) to feed into. I could drill a hole through my brick to lead it to my backyard, but I don't know if I want the acidic condensate draining onto my nice patio tiles!

Am I missing something or is there something better I can do to deal with this condensate?

for around 50 bucks you can get a small condensate pump and pump the water to a laundry standpipe. the discharge is only 3/8 soft tubing.

You might want to add a condensate neutralizer to the line as well. The condensate is very corrosive and can eat away clay and steel pipe over time.
